Male Roller Derby
The all-female revival of roller derby led to the introduction of all-male teams with the Men’s Roller Derby Association (MRDA), which is currently the international governing organization for men’s flat-track roller derby. The group was founded in 2007 and has 65 leagues under its jurisdiction.
Other Leagues
Other leagues, mostly mixed-gender, do not compete in regular seasons, but rather schedule occasional special-event games for a handful of spectators. Team names generally pay homage to Roller Derby and Roller Games teams of the past. There are currently over 2,000 amateur leagues worldwide.
